Version-Release number of selected component (if applicable): memtest86+ 4.20 from Fedora 17 Alpha DVD How reproducible: always Steps to Reproduce: 1. qemu-kvm -m 1024 -cdrom Fedora-17-Alpha-x86_64.DVD.iso 2. choose Troubleshooting => Run memory test Actual results: see the attached screenshot Expected results: no errors Additional info: Initially, I've run this on Intel SandyBridge hardware - Pentium B950 with some Samsung memories, and it failed this way, leading me to unjustified warranty claim ... After that, I've verified the same memtest behaviour on T510 with Core i7 M620, and on some older desktop with Core i5 - real hardware, proven by months of service => seeing the same all the time I've tried in qemu and it fails too.

It seems to be related to gcc-4.7 update. Temporal workaround patch is attached (it could negatively affect performance).

Criterion: "All release media must include a standalone memory test utility. A boot menu option to launch this utility must be present and must work correctly. " Also proposing as Beta NTH, it would be good to ensure the memtest in Beta works. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Reply at: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1071209/comments/4 ------------------------------------------------------------------------ On 2012-03-28T05:59:57+00:00 Fedora wrote: Package memtest86+-4.20-6.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days.

Accepted as NTH: this can't be fixed with an update, and it's obviously visibly bad to have broken memtest on our beta images. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Reply at: https://bugs.launchpad.net/ubuntu/+source/memtest86+/+bug/1071209/comments/7 ------------------------------------------------------------------------ On 2012-03-29T04:12:23+00:00 Fedora wrote: memtest86+-4.20-6.fc17 has been pushed to the Fedora 17 stable repository.
